NASA is troubleshooting a glitch with the upper stage of Artemis 2's Space Launch System rocket that will likely delay the launch of the moon mission.

NASA revealed the latest problem just one day after targeting March 6 for Artemis II, humanity’s first flight to the moon in more than half a century. Overnight, the flow of helium to the rocket’s upper stage was interrupted,

In the latest setback to return astronauts to the moon, NASA delayed the highly anticipated flight yet again after a new problem cropped up with the rocket Saturday. April is now the earliest that the four Artemis II astronauts could fly to the moon.

NASA found an issue with helium flow in the upper stage of the Space Launch System rocket, prompting engineers to prep for a rollback. Artemis II will miss its March launch window.

NASA's long-awaited mission to the moon has been delayed. The Artemis II mission will send four astronauts on a 10-day fly around the far side of the Moon and back to Earth again. After a successful dress rehearsal - or wet rehearsal - on Thursday,

NASA aims to launch its next crewed moon mission, Artemis II, as soon as March 6, after a key fueling test showed major progress and only minor issues. Mission managers said the latest wet dress rehearsal — a full practice run that involves loading the Space Launch System rocket with super-cold liquid fuel — met all the main goals.

NASA has delayed the first crewed lunar mission since 1972 after technical problems forced the US space agency to push back the launch of Artemis 2 by several weeks. NASA said in a statement on

NASA chief Jared Isaacman on Saturday ruled out a March launch for Artemis 2, the first crewed flyby mission to the Moon in more than 50 years, citing technical issues.
